Title: High capacity flat FET - supports high voltage in blocked state and uses double grille system of doped areas
Inventor: BARANDON RENE
IPC: H01L29/808
Filed: 1975-03-06
Abstract: On the lower face of the flat support there is a N type contact layer (8). On the upper face of the support (2) P type impurities are diffused to form a lower grille (10). The arrangement of the bars and the gaps between them form the lower control layer. The part of the support (2) situated between this control layer and the lower contact layer (8) forms a base layer. On the upper part of the support (2) after formation of the bars (10) an epitaxial layer of N type silicon is formed. At the surface of this epitaxial layer on upper grille of strong P type doping bars (14) having gaps (12) parallel to the bars (10) is formed, and between the bars (14) are contact zones (16) of strong N type doping. These contact zones (16) are arranged above and on the median axis of the bars (10).

Title: Cabbage prepn for sauerkraut - in machine for stack boring, topping, tailing, loose leaf shedding and brushing
IPC: A23N15/00
Filed: 1975-03-28
Abstract: Heads of cabbage are prepared for the mfr. of saukeraut (pickled cabbage) in a machine where the height of each head is measured and the depth required to bore out the stalk is set accordingly.
